How to generate the readout

The readouts are defined in a RML file, in this case in readouts_IAXOD0.rml. This file contains definitions for multiple readouts which correspond to the section called TRestDetectorReadout with name given by the field name.

In order to generate the readout.root file follow this instructions. We use a RML file called readouts_IAXOD0.rml which contains the readout named IAXOD0_Readout.

• Open a ROOT prompt and load REST libraries (type restRoot).

• From the ROOT shell create a new TRestDetectorReadout object referencing the RML file and the name of the readout to use

TRestDetectorReadout *readout = new TRestDetectorReadout("readouts_IAXOD0.rml", "iaxo_readout").

• Create a ROOT file to save the readout into

TFile *f = new TFile("readouts.root", "RECREATE").

• Save the readout with a name of our choice which will be used to reference this readout inside the file (in this case "iaxo_readout"). One can create multiple readouts and save them all to the same, then we can choose to load the one we need. To add a new readout to an existing readouts.root file, use the option "UPDATE" instead of "RECREATE".

readout->Write("iaxo_readout").

• Safely close the file

f->Close()
